Since you have found this site it is likely that you have read at least one of Daniel Quinn's books. I'll list them here for easy reference for those who have not read all of them.
Ishmael The book that started it all. If you haven't read any of Quinn's work, this is where you should begin. Available in paperback.
ProvidenceThis book in non-fiction and autobiographical. If you want to understand more about why Daniel Quinn wrote Ishmael, this is the book to read.
The Story of B This is a much harder hitting book than Ishmael. It also delves more deeply into some of the issues. Not for the faint of heart.
My Ishmael Daniel Quinn's newest work is now available. Another of Ishmael's students, tells what she learned from Ishmael. Topics include tribalism, unschooling, the development of agriculture, locking up the food, Leaver economies and breaking free of the Taker prison. If you have had lingering questions, this book may answer some.
